The procedure that i talk to you (implementing in Brasil to solve the
problem -Stratum with single PSU) - it�s alocate the single PSU in
other stratum. The question "which stratum" depend design sample that
you work. In my estimation - Im working with Brasil agregated (data
with 400.000 value per year with information: weight, psu, stratum)
when I have this problem (single PSU) - I do agregation to other
stratum in the same State with more number of value. It�s a sugestion
to solve this problem and I dont have idea that it�s the best thing to
do (in statistical point but I�t a sugestion official departament that
do the research).
My do-file (algorithms) run all de 400.000 value, check for the
stratum with single PSU, agregate this stratum to other stratum with
more high value data (in the same State) and I dont have more the
errors that you talk! I could send my do files for you but you need to
write one for you specific design sample.
